I build AI systemsthat do the workyou'd rather not.

I work with fast-moving companies that have real technical problems. I build things that run in production, not demos that live in slide decks.

What I build for clients.

01

AI Systems & Agents

Production-grade LLM agents, RAG pipelines, and agentic workflows. From multi-tool function-calling agents to automated data ingestion with n8n and Supabase.

Mobile & Web Development

React Native apps for iOS and Android, Next.js web apps, or anything in between. I ship fast and don't cut corners on performance.

About

Built by someone who's done it.

Simon Harrysson

I'm Simon, 23. I wrote my first Java program at 13, had my first app on the App Store at 14, and haven't been able to stop since. I study CS and ML in Linköping and build AI systems in the time between lectures. There's always a problem running somewhere in the back of my head — on a run, between lectures, right before sleep.

How it works

No pitch. Just a conversation.

We'll spend 30 minutes looking at your work together and figure out what makes sense to automate.

1

Book a slot

Pick a time that works for you. No prep, no forms, no brief to fill out beforehand.

2

Walk me through your work

Tell me what a normal week looks like. We find the tasks that eat time and shouldn't need a human.

3

You decide what happens next

If there's a clear fit, we scope it out together. If there isn't, you've lost 30 minutes and gained a bit of clarity.

Book a call

Let's find 30 minutes.

Pick a 30-minute discovery call if you have a project in mind, or a 15-minute intro if you just want to get a feel for whether I'm the right fit. No prep needed.
